All Andrews cam kits for early Twin Cam '88 models require a new heat-treated 34-tooth rear cam drive sprocket and 17-tooth front cam sprocket. The new sprocket replaces OEM sprockets. As of winter '99, no Andrews Twin Cam 88 cam sets will be sold without one new drive sprocket. Sprockets are made from heat-treated alloy steel and are longer than stock for greater stability. A full-lenght 3/16" drive key and 3 spacer shims are included. With the shims, the installed lenght of new sprocket can be set to the same lenght as the original stock sprocket plus spacer. 34 tooth and drive sprocket will fit all Twin Cam '88 model rear cam shafts. If you are into any performance riding, a new sprocket is a must installation, even with engines using stock camshafts.
